yawns

I'm a little stuck... Click here to teach me more about this clue!

'jaw-dropping activities' is the definition.
'yawns' can be an answer for 'activities' (yawn is a kind of activity). I'm not sure about the 'jaw-dropping' bit.

I don't understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for yawns that I've seen before include "Gapes" , "Signs of fatigue or boredom" , "seems tired" , "Expresses no interest" .)
